Abstract

Apparatuses, methods and systems for beamforming based on encoding are disclosed. One embodiment of a method includes generating a beamforming matrix, including obtaining a channel matrix of a multiple-input, multiple-output (MIMO) channel between multiple transmitter antennas and at least one receiver antenna, determining an initial beamforming matrix based on a singular value decomposition of the channel matrix, and generating, by a transceiver, a final beamforming matrix comprising reordering columns of the initial beamforming matrix for at least one sub-carrier of a multi-carrier signal, wherein the reordering of the columns is based on knowledge of encoding of a transmit signal.
